necessary.  If  information  is  available  and pertinent to the message, include optional sets. Conditional   sets   are   EXER/OPER   and NARR/AMPN. When using optional sets, use one  set  at  a  time.  Never  use  optional  sets together. When using the REF (Reference) set, you should use the AMPN or the NARR set. Use the AMPN (Amplification) set if there is only one reference. Use the NARR (Narrative) set when there are multiple  references.  A  reference  may  be  a meeting,  conversation,  document,  letter,  or record message. Refer to the NTP 3 for the appropriate message reference identifier. Be careful when drafting the addressee portion of naval messages. Your command should have the Distributed Plain Language Address (PLA) Verification System (DPVS) installed on all computers that have the MTF Editor. DPVS provides naval message originators with current single and collective PLA information. PLAs may  also  be  found  on  the  Internet.  This information   ensures   that   messages   are transmitted to activities that are supposed to receive them. If an addressee does not appear in DPVS, verify the address. If your command does not have DPVS, it is available from the local Navy telecommunications center. Copy all outgoing messages to a diskette for delivery  to  the  Navy  telecommunications  center. Ensure that the diskette is properly marked with the highest precedence of the content of the disk, the name of your activity, and your telephone number. Deliver a properly formatted disk that is free of computer viruses. Remember that a designated message releaser should sign outgoing naval messages. Q9. Q10. Q11. Q12.

DIRECTIVES ISSUANCE SYSTEM LEARNING  OBJECTIVES:  Describe  the purpose of the Directive Issuance System. Identify   the   types   of   directives,   their numbering  system,  and  directive  security identification. The directives issuance system provides a uniform method for issuing directives by all naval activities. As set forth in the Department of the Navy Directives Issuance System, SECNAVINST 5215.1, the directive issuance system contains two parts. Part I contains Definitions,  Criteria,  and  Responsibilities  for  issuing directives.   Part   II   contains   Preparation   and Maintenance of Directives procedures. The directives issuance  system  is  used  in  conjunction  with  the Department of the Navy File Maintenance Procedures and  Standard  Subject  Identification  Codes  (SSIC), SECNAVINST 5210.11. SECNAVINST 5210.11 provides the Navy with a standardized file numbering system  to  efficiently  manage  large  volumes  of paperwork, so Navy personnel have the same filing system from one activity to another. The file numbering system is based on SSICs. SSICs indicate the subject and may be used to identify the document for filing purposes.  The  SSIC  is  also  used  when  naval correspondence is prepared. SCOPE In  the  directives  issuance  system,  a  directive  is defined as a written communication that prescribes or 2-17
